防屈曲耗能支撑技术研究与工程应用

山西省图书馆新楼为不规则框架结构,为了抵抗平面扭转,在楼梯及转角部位设置了防屈曲耗能支撑,替代了混凝土支撑与钢支撑,提供同样的刚度,耗能性能与抗震稳定性大大提高,而且起到提高结构阻尼的效果。介绍了防屈曲耗能支撑原理、布置原则、材料要求、连接方法、施工安装及质量验收。

The Technology Research and Engineering Application of Buckling-restrained Braces (BRB)

The new building of Shanxi Library has the irregular frame structure,in order to resist the plain torsion,the BRB was set up on the stairs and the corner areas,which replaces the concrete support and steel support,provides the same stiffness,improves greatly the energy consumption and the seismic stability,and improves the structural damping effect. This paper introduces the theories,layout principles,material requirements,connecting methods,construction installation and quality inspection of BRB.
